Running brain. Conceptual computer artwork of a human brain running on human legs. This could represent the speed of thought, or pyschological concepts such as denial, fear of commitment, and phobias. The human brain, located in the head, is a complex organ. Some areas deal with the conscious muscle control, balance and vision used in running, while other areas deal with autonomic functions such as breathing and heart rate, and other areas deal with higher functions such as memory, language and thought.
